Are alkali metals found as pure elements in sea water?
Alkali metals exist only as salts.
Does neon react vigorously with alkali metals to form salts?
No, cesium is an alkali metal. Metals do not react with one another. Cesium reacts with nonmetals and acids to form salts.
Why are the reagents used to test for cations usually alkali metal salts or ammonium salts rather than salts of other metals?
because poo is black
What charge do alkali metals form when they react with a halogen?
here r the possisble answers: both atoms lose 1 electron a covalent bond forms metal gains an electron and the nonmetal loses an electron metal loses an electron and non metal gains an electron
What happens when you react an alkali metal with a metalloid?
They combine directly to form salts. E.g. lithium + fluorine -- > lithium fluoride if i am not mistaken..
Are alkali metals found as pure elements in sea water?
Alkali metals exist only as salts.
Most salts (alkali metals)?
Li, Na, K, NH4
What are the examples of weak salts?
These salts are weak electrolytes: examples are acetates, formates etc. of alkali metals.
What salts are soluble?
Those salts which can dissolve in water.because water is a solvent and salts are solute.
Halogens form what when mixed with alkali metals?
The products of the reactions are ionic salts.
Which group reacts with alkali metals to from salts?
Halogens, such as chlorine, iodine or fluorine.
Does neon react vigorously with alkali metals to form salts?
No, cesium is an alkali metal. Metals do not react with one another. Cesium reacts with nonmetals and acids to form salts.
Most salts (alkali metals) of Li, Na, K, NH4?
Rule 2
Compound that forms hydroxide ions in solution?
Hydroxide salts from (mainly) alkali and some earth-alkali metals.
Why are the reagents used to test for cations usually alkali metal salts or ammonium salts rather than salts of other metals?
because poo is black
Are chromates salts soluble?
Chromates of Alkali metals are soluble, but most other chromates are insoluble
Why presence of salts hasten rusting?
Halogens ions from alkali metals halides have a corrosive effect on materials.
